php封装的 HttpCurl类

封装的 HttpCurl类,实用比较灵活.

废话不多说啦.直接放代码啦!

<?php
 
/**
 * Curl Class
 */
class HttpCurl
{
    /**
     * 模拟 POST 与 GET 请求
     *
     * Examples:
     * ```
     * HttpCurl::request('https://blog.kieng.cn', 'post', array(
     *  'user_uid' => 'root',
     *  'user_pwd' => '123456'
     * ));
     *
     * HttpCurl::request('https://blog.kieng.cn', 'post', '{"name": "peter"}');
     *
     * HttpCurl::request('https://blog.kieng.cn', 'post', array(
     *  'file1' => '@/data/sky.jpg',
     *  'file2' => '@/data/bird.jpg'
     * ));
     *
     * // windows
     * HttpCurl::request('https://blog.kieng.cn', 'post', array(
     *  'file1' => '@G:\wamp\www\data.jpg',
     *  'file2' => '@G:\wamp\www\data.jpg'
     * ));
     *
     * HttpCurl::request('https://blog.kieng.cn', 'get');
     *
     * HttpCurl::request('https://blog.kieng.cn?a=123', 'get', array('b'=>456));
     * ```
     *
     * @param string $url [请求地址]
     * @param string $type [请求方式 post or get]
     * @param bool|string|array $data [传递的参数]
     * @param array $header [可选：请求头] eg: ['Content-Type:application/json']
     * @param boolean $gzip [可选：GZIP 压缩]
     * @param boolean $redirect [可选：重定向跳转]
     * @param int $timeout [可选：超时时间]
     *
     * @return array($body, $header, $status, $errno, $error)
     * - $body string [响应正文]
     * - $header string [响应头]
     * - $status array [响应状态]
     * - $errno int [错误码]
     * - $error string [错误描述]
